Thromboembolic events represent the main cause of morbidity and mortality in patients with polycythemia vera. Leukocytosis has been identified as an important risk factor for development vascular thrombosis. A 47-year-old woman vera presented pain swelling her right calf. She was scheduled to receive anagrelide which effective on thrombocytosis, but leukocytosis persisted. diagnosed thrombosis ...

OBJECTIVES Our purpose was to investigate cervical lymphadenopathies by using color Doppler spectral analysis and power Doppler ultrasonography methods as well as B-mode ultrasound and to classify them as malignant or benign lesions and to compare the results with the histopathological findings. PATIENTS AND METHODS Sixty-nine lymph nodes of 69 patients were evaluated with color and power Dop...

The purpose of this article is to review the current knowledge about ultrasonography of head and neck lymph nodes in order to enable the ENT specialist to differentiate benign versus malignant masses. All classic ultrasonographic criteria (size, shape, hilum, echogenicity, margins, structural changes, edema, Doppler flow, vessel location, vascular pedicles and pattern) are explained with an emp...

BACKGROUND We evaluated the long term clinical outcomes of femoral vascular closure devices following its deployment in coronary angiography and percutaneous coronary intervention (PCI) procedures. METHODS From June 2000 to September 2004, 265 patients who received femoral vascular closure devices after coronary angiography and PCIs were enrolled into the study. Patients' medical records were...

Distribution of atherosclerotic vascular lesions in the intracranial posterior circulation has not been as well documented as in the anterior circulation. Data regarding this aspect among Asian stroke patients are scarce. In present study, we sought to investigate the distribution of posterior circulation vascular lesions in Chinese stroke patients. We examined consecutive patients with acute i...

Background: Vascular leiomyosarcoma is a rare but most common vascular tumor of the inferior vena cava.Case presentation: We present case an incidentally diagnosed extraluminal cava in 62 year old patient who presented with abdominal pain following blunt trauma. Ultrasonography showed lobulated hypoechoic lesion upper abdomen. Computed tomography (CT) and magnetic resonance imaging (MRI) circum...

OBJECTIVE The aim of our study was to investigate the use of targeted contrast-enhanced high-frequency ultrasonography for molecular imaging of vascular endothelial growth factor receptor 2 (VEGFR2) expression on tumor vascular endothelium in murine models of breast cancer. METHODS Highly invasive metastatic (4T1) and nonmetatstatic (67NR) breast cancer cells were implanted in athymic nude mi...

Objective: Vascular tumors of the breast are extremely rare; among these tumors, hemangiomas without pathognomonic features. Hemangiomas incidentally seen in mastectomy cases. Diagnosis using conventional imaging methods is rare. Core needle biopsy and aspiration cannot help diagnosis. Case: A 69-year-old woman presented to outpatient clinic with a sudden hematoma on slow-growing mass right 1-y...
